As anticipated, Facebook filed its initial public offering late last night seeking $5 billion in funding. Inside its filed prospectus, Facebook revealed some great statistics; like how the company had reached 845 million monthly active users by December 2011 and how they shared 100 billion friendships.

Facebook is set to reach one billion active users by August of this year, according to research from iCrossing. Facebook, comfortably the world's largest social network, currently has in excess of 800 million active users.

A little over one month since launching initially in the United States, and Brazil a few days ago, iTunes Match is now available in a number of new countries, including Australia, Canada, Germany, Ireland, Mexico, New Zealand, the United Kingdom, and possibly unconfirmed others.

The Brazilian government has announced the discovery of a previously unknown tribe of people living deep in the Amazon rainforest. The tribe was first discovered when satellite imagery showed clearings which were likely caused by human activity. Funai, the Brazilian Government agency responsible for the protection of indigenous tribes later confirmed their existence during a fly-past in April.

While Facebook is still experiencing user growth, having reached 687 million monthly active users at the start of this month, this growth rate has been lower than normal for the second consecutive month, according to Inside Facebook.
